A reflexive relation that is also transitive is a preorder. 满足传递性的自反关系称为预序关系。
In addition, rough entropy which is based on fuzzy reflexive relation is discussed by the cut sets. 另外,运用截集的思想讨论了模糊自反关系下的粗糙熵,并给出了粗糙熵的一种新定义。

Rough Entropy and Granularity Measure to Incomplete Information System Under the Reflexive Binary Relation 自反二元关系下不完备信息系统的粗糙熵及粒度度量
This paper gives a new concept of reflexive closure of fuzzy relation and symmetric closure of fuzzy relation, and also gives operation method and properties about it. 本文定义了模糊关系的自反闭包、对称闭包概念,同时给出了模糊关系的自反闭包、对称闭包的运算方法及性质.打破了在原有的模糊关系只有传递闭包的局面。
